2. G5 Mobile app (app) on your smart device
While the system works with different smart devices, they’re not
interchangeable during a sensor session, so before starting one, select which
smart device you want to use and stick with it throughout your session. You
can’t use multiple smart devices at the same time, but you can combine the
receiver with a smart device during a session.
The G5x is the first CGM system where a smart device acts as a receiver. For
a list of current devices and operating systems, go to:
dexcom.com/compatibility.
Chapter 5 covers how to set up your smart device with the app.
The primary difference between the receiver and app is not the information
they give you, but how that information is presented. The following are some
of the shared CGM data and system information features.
Tracking Real-Time CGM Data
The receiver and app give you the ability to track your glucose trends in a
number of different ways. Each device’s home screen opens to your glucose
trend screen.
Viewing Glucose Levels
The receiver and app share many of the same glucose-monitoring features.
Your glucose values are color-coded to highlight what zone you are in,
allowing you, at a glance, to see what your levels are.
Color-coded glucose levels:
• Red - Low
• Gray - Within your target range
• Yellow – High
Trend Arrows
Glucose levels are not just about the numbers. The G5x includes trend arrows
so you know the speed and direction of your glucose, allowing you to
proactively react before your glucose gets too high or too low.
